Dose 2016

Q2:

Being D

w the dose absorbed at a point in water and D det

the averaged absorbed dose in the detector placed at that point . What of the following equalities is true?

1. D

(P) = D

(P)

det

w

2. D

(P) x f (Q) = D w

(P)

det

3. D

(P) x CF = D w

(P)

det

4. D

(P) = D

(P’)

det

w

Where f(Q) is the cavity factor and depends on the quality of the beam

Where CF is a calibration coefficient that is independent of the beam quality
